To all u'l'io'm it may toilet/n:

ii i linen-ii that 1. JOHN Licon, it citizen oi the United States. and a resident oi tliicago, in the county of l eol; and State of Illinois, have invented certain new afford an antilrici ion hearing between the holster and truck upon the occa on of relative angular movement of the ear and truck, 211E when the (or is passing around ll curve.

The invention consists in the matters hereinafter set l'nri h :1 nd more particularly pointed out in the append ed elnnns.

Anion the objects ol the invention is to-improve and simplify the construction of bearings of this character, t! minimize the liiibility of breakage of the bearing roller tl 'l n5; during use or tinnsportution oi the bearing, to hti'ilililtt' the placing and the removal of the roller into llll l [min the casing, and to produce it betiringlnn'ing these elmmeteristies which may be economically manuhtetnred.

lo the drawing; ''Figure 1 illustrates the manner in which my improved beiiring isnttached 11013110 truck nnd cur hols-term a. railway car. 1 Fig. 2 is a longitudinal section oi the upper benrlng easing illustrating the roller and lower bearing member in side elevation. Fig. 3 is :1 bottom plan view of the bearing member. Fig. 4 is 21 minsverse section, taken on line 44 oil Fig. 2. Fig. 5 is n shit:- eleviition of the upper bearing. 1

As snown in the drawings, it. represents LL- portion of th body holster oi the car and B the corresponding part of th truck. Said truck is provided with shearing member or plute t. lnivingnn upwardly facing hearing st 1 ri'u ce.

ing uieniber, designated as a. whole in Fig. l by D. Said miner hearing nieinher consists generally or" a. cast metal (using l) lot-med to provide a longitudinal, downwardly opening roller chamber D having it its top a down- ."tlly lacing bearing surface (I, and one or more rollers l sted in said chzunber and projecting through the lower open side tuereoi' for contact with the upper surof the hearing plate (1 and adapted for engagement also with the honing surface J. it is with respect to the upper bearing member to wliicl'i the present inventioii relates. 'lhe said. casing comprises 2b top Wall, on l the trunnion recess .s, are thinner thou the other ports I A t to ehed to the lower side of the body bolster, yert icnlly (lb!) ve sold bearing plate 0, is the upper bear the lower side of which is formed the hearing snrl'nce (7, side walls cl and end walls (F (P. the said walls inelosing the bearing roller eliuuiher D The easing; is innit-lied tothe body hostel" by means of apertured lugs 1] it. the latter arranged in i pair on one side ol the (using, and the other singly on the other side thereof. The side walls .of the casing are formed to provide rece :cs d which receive the trunnions or end bearings f of the roller.

In accordance with my invention, thojlowor walls of said trunnion recesses, which constitute trucks upon which the roller is supported when it drops out or con-- tact with the upper bearing surface d, comprise continuous bars'or plates G G that are separate from and reniovahly titted to the lower side of the c: sing in such 1112141116! that the removal of said track bars iits the roller to be freely inserted into-or removed irom the roller chamber. vlhen said bars are titted to the cits ing, the roller is held in place thereby. The upper feces of said bars are continuous thereby affording a continuous track for the trunnions of the rollers when the roller is supported thereby. As herein shown, said tracks are curved downwardly from .ezteh end of the casing towards the center thereof, whereby the roller is self-centered when supported on the. trucks, as. in the construction ol the Woods patent before referred to. The trunnion recesses are made of such width that the roller has Vei'llcttl movement in the casing relatively to the tracks, as well as longitudinal movement thereon, due to the length (if-the roller casing. As heroin shown, said truck bars are formed parts of an integral costing; being joined at their ends by integral transverse pieces G G. The snid costing embracing said truck bars is attachcdto said casing, in the present construction, l'iy means of rivets or bolts H H. extending horizontally through t1])t,lllll0l extensions or lugs d" a' at the ends of said casing and through zipertured ears g g tit the endsfX of said track bur lrznne, which ears overlap said casing lugs In order to prevent too great stress being brought; upon the ears or lu due to lateral press re thereon, the said tnul; bur l'rzinie is provided zit its sides with longitudinal ribs or flanges g g which iii into complementul longitudinal recesses formed in the outer sides of the lower margins of the side walls of the casing, as most clearly shown in Fig. l.

In practice, the main body ol the casing may be made. of cast steel, suitably chilled to form the top hearing surt'tice of the roller clnunber, (or a hardened plate may be inserted thereiin) while the lower member thereof, constituting the tracks for the trunnions or end hearings of the roller, may be made ol malleable iron.
